Mario Stifano, the Executive Chairman of the Corporation, Ernest Mast, the President and Chief Executive Officer and a director of the Corporation, 1974899 Ontario Ltd. ("1974899"), a corporation wholly-owned by Gavin Nelson, the Chief Financial Officer of the Corporation, and funds managed by Equinox Partners Investment Management, LLC ("Equinox Partners"), an insider of the Corporation, subscribed for 125,000 Offered Common Shares, 208,334 Traditional Flow-Through Shares, 100,000 Offered Common Shares and 500,000 Offered Common Shares, respectively, under the Offering on the same terms as arm's length investors. Additionally, the Corporation understands that funds managed by Equinox Partners were party to an arrangement with the initial subscribers of the Charitable Flow-Through Shares or donees thereof, pursuant to which funds managed by Equinox Partners purchased 2,875,000 common shares in the capital of the Corporation. The participation of Messrs. Stifano and Mast, 1974899 and Equinox Partners in the Offering constitutes a "related party transaction" for the purposes of Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions ("MI 61-101"). The Corporation is exempt from the requirements to obtain a formal valuation or minority shareholder approval in connection with the Offering in reliance on sections 5.5(a) and 5.7(1)(a), respectively, of MI 61-101, as neither the fair market value of the securities issued to the related parties nor the fair market value of the consideration for the securities issued to the related parties exceeds 25% of the Corporation's market capitalization as calculated in accordance with MI 61-101. The Corporation did not file a material change report more than 21 days before the expected closing date of the Offering as the aforementioned insider participation had not been confirmed at that time and the Corporation wished to close the Offering as expeditiously as possible.

The Offering was made by way of private placement in each of the provinces of Canada pursuant to applicable exemptions from the prospectus requirements and, in the case of the Offered Common Shares, in certain other jurisdictions, in each case in accordance with all applicable laws. The Offering of the Offered Common Shares was conducted on a private placement basis to persons in the United States who are "accredited investors", as such term is defined in Rule 501(a) of Regulation D ("Regulation D") under the United States Securities Act of 1933, as amended (the "U.S. Securities Act"), and in compliance with Rule 506(b) of Regulation D and applicable United States securities laws. The securities issued under the Offering are subject to a four month hold period under applicable Canadian securities laws which will expire on October 7, 2023. The Offering is subject to final acceptance of the TSX Venture Exchange.

The securities offered have not been, nor will they be, registered under the U.S. Securities Act or any state securities law, and may not be offered, sold or delivered, directly or indirectly, within the United States, or to or for the account or benefit of U.S. persons, absent registration or an exemption from such registration requirements. This news release does not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of securities in any state in the United States in which such offer, solicitation or sale would be unlawful.
